2018-04-28DWARF: Add .debug_addr table header for dwarf_version >= 5.Mark Wielaard2-1/+31
GNU DebugFission didn't add table headers for the .debug_addr tables, but DWARF5 does. The table header makes it possible for a DWARF consumer to parse the address tables without having to index all .debug_info CUs first. We can keep using the .debug_addr section label as is, because the DW_AT_[GNU_]addr_base attribute points at the actual address index, which starts right after the table header. So the label is generated at the correct location whether the header is added first or not. Add DW_AT_addr_base instead of DW_AT_GNU_addr_base to the skeleton CU DIE for DWARF5. gcc/ChangeLog * dwarf2out.c (dwarf2out_finish): Add .debug_addr table header for dwarf_version >= 5.

Given that the SVR4 vs PLT code model consideration is irrelevant for this test case rather than rewriting the regular expression to match this variant of code just enforce the PLT model by using the `-mplt' option.

2018-04-25DWARF sort longer dirs before shorter ones in directory table.Mark Wielaard2-4/+12
When gcc dwarf2out generates the .debug_line table itself (for example when generating one for a split DWARF .dwo) it uses natural sorting for the directory table. Shorter directory paths come before longer directory paths with the same prefix. This causes the files in the line table to pick the shorter dir. Creating slightly ineffecient line tables because the longer directory paths will never be used. Fix this by changing file_info_cmp () to pick longer directory prefixes before shorter ones. We still sort files (the compilation unit) without any directory path before all entries with a directory path, so they will still use dir entry 0 (the working directory). A hello.c program would get the following dir and line table before: Directory table: /opt/local/install/gcc/lib/gcc/x86_64-pc-linux-gnu/8.0.1/include /usr/include /usr/include/bits File name table: Entry Dir Time Size Name 1 0 0 0 hello.c 2 1 0 0 stddef.h 3 2 0 0 bits/types.h 4 2 0 0 libio.h 5 2 0 0 stdio.h 6 2 0 0 bits/sys_errlist.h Note that the last directory table entry is never used. After this patch it looks as follows: Directory table: /opt/local/install/gcc/lib/gcc/x86_64-pc-linux-gnu/8.0.1/include /usr/include/bits /usr/include File name table: Entry Dir Time Size Name 1 0 0 0 hello.c 2 1 0 0 stddef.h 3 2 0 0 types.h 4 3 0 0 libio.h 5 3 0 0 stdio.h 6 2 0 0 sys_errlist.h Which is similar to what gas would output. gcc/ChangeLog: * dwarf2out.c (file_info_cmp): Sort longer dir prefixes before shorter ones.

* config/i386/i386.md (*x86_mov<mode>cc_0_m1): Use type "alu1" rather than "alu", remove explicit "memory" and "imm_disp" attributes. (*x86_mov<mode>cc_0_m1_se, *x86_mov<mode>cc_0_m1_neg): Likewise. From-SVN: r259650
